Use the
Multiselect [
^]property and loop through the FileName list.
Something like this. The code is in C#, but should give you an idea.
OpenFileDialog dlg = new OpenFileDialog();
dlg.Multiselect = true;
if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
foreach (string file in dlg.FileNames)
{
FileInfo fileInfo = new FileInfo(file);
fileInfo.CopyTo(@"D:\foldername\", true);
}
}
